SYSTEMS VERIFICATION - 2021/2
Module code: COM3028
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
The course is an introduction in formal methods for system specification and verification.
It will focus on logic-based formalisms and techniques, and specifically on model checking.
The main logics taught will be temporal logics, which are mainstream in verification, especially analysis of hardware systems.
Other logics and verification techniques (such as theorem proving) will be included to a smaller extended.
Model checkers will be used in the labs, on different system-verification problems.
Elements of building model checking tools will be presented and explored.
Some elements of advanced verification techniques (e.g., abstraction) will be mentioned.

|Assessment type||Unit of assessment||Weighting|
The assessment strategy is designed to provide students with the opportunity to demonstrate that they have achieved the module learning outcomes.
Thus, the summative assessment for this module consists of:
· First individual coursework on temporal logic and explicit model checking. This addresses LO1 and LO2.
· Second individual coursework on applied non-classical logics, symbolic model checking of temporal logics and/or other verification techniques for applied logics (e.g., program verification with Hoare logic) . This addresses LO1 and LO2.
· A 2h unseen examination on the whole course content. This addresses LO1, LO2, LO3, LO4.
The individual pieces of coursework will be due around week 5 and 10 respectively. There will be five labs and the best four submissions of the total five will be considered towards the lab component of the mark. The exam will take place at the end of the semester during the exam period.
Formative assessment and feedback
1. PollEverywhere or other interactive polling methods will be used in the lectures with each lecture consisting of a number of slides explaining the theory followed by a number of slides gauging the students’ understanding. The answers are discussed when necessary, e.g., if a high proportion (more than 25%) of the students got the answer wrong.
2. Individual formative feedback will also be given during the lab sessions, and as part of the summative assessment.
Assessment & Assessment Strategy: Executive Summary
Coursework 1 (15%) -- take-home work, testing learning outcomes 1 and 2
Coursework 2 (15%) -- take-home work, testing learning outcomes 1 and 2
Final exam (70%) -- unseen written piece of examination in the exam period, testing learning outcomes 1, 2, 3 and 4

Overall student workload
Independent Study Hours: 110
Lecture Hours: 24
Tutorial Hours: 6
Laboratory Hours: 10
Methods of Teaching / Learning
The learning and teaching strategy is designed to develop a critical understanding of the foundations of systems verification, facilitating self-directed further studying in this field.
The skills learned in this module will be transferable to other verification techniques, such as program analysis.
Also developing critical thinking is at the core of this module.
The learning and teaching methods include:
- Twenty-four hours of lectures with class discussion
- Ten hours of tutorials
- Six hours of lab classes
- Use of an online forum for facilitated discussion
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
